Mary Ross Ellingson

Mary Ross Ellingson (1906 – 1993) was a Canadian archaeologist who worked on the excavations at Olynthus in Greece, where she focused on the use of terracotta figurines in ancient Greece. She did not receive due credit for her work at the time because her research was published by her mentor, David Moore Robinson, under his own name. Robinson's plagiarism of her work only came to light in 2014.

Early years Helen Madeline Mary Ross was born in 1906 in Edmonton, Alberta, Canada, and went on to study at the University of Alberta. During her undergraduate years, she studied classical languages and culture and showed an interest in journalism. She served as editor of The Gateway newspaper and submitted articles to a local non-collegiate newspaper, The Edmonton Bulletin.

After her 1939 marriage to Rudolph Conrad Ellingson, who received his doctorate in chemistry from Johns Hopkins University, she was known as Mary Ross Ellingson.

Ellingson appears to have left academia after getting her doctorate, although Robinson mentions her as teaching at Mount Royal College in Calgary, Canada, in the early 1950s.
